DOOR-CLOSER.

SPECIFICATION forming part of Letters Patent No. 643,970, dated. February 20, 1900-.

Application filed April 8, 1899- Serial No. 712,245. (No model.)

To all whom it may concern:

Be it known that I, JAMES EKMQFEELY, of Pueblo, in the county of Pueblo and State of Colorado, have invented a new and Improved Door-Closer, of which the following is a full, clear, and exact description.

The object of my invention is to provide a simple and inexpensive device capable of attachment to any swing-door and to so construct the device that during the act of opening a door sufficient power will be stored or accumulated to enable the device to automatically close the door. I

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawin gs,formin g a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure lisafront elevation of theimproved device in position upon thedoor. Fig. 2 is a vertical section through the door and an end view of the device. Fig. 3 is a verticalsection through the door and device, the section being taken practically on theline 3 3 of Fig. 1. Fig. 4 is a vertical section through the wheel of the device adapted to travel 'upon the floor and a portion of the shaft to which said wheel is secured. Fig. 5 is a detail perspective view of one of the bearing-blocks for the wheel-shaft.

The frame or body portion of the deviceconsists of a back plate A, adapted to be secured to the lower swing corner of a door, at the inner face of the latter, and this plate is provided with an opening 10, as shown best in Fig. 1. Two box-casings B and B are secured to the outer face of the plate A. The front faces of the box-casings are usually cylindrical, or practically so, and the said boxcasings are open at the bottom, as shown in Figs. 1 and 3. The box-casing B is provided with an outer side section 11 and an inner side section 12, while the box-casing B is provided with an outer side'section 13 and an inner side section 14, a space being made to intervene the two inner sidesections of the box casings. The box-casing B is wider than the casing 13 and is provided with a central partition 15 of the same character as the side sections 11 and 12. A vertical slot 16 is made in the bottom edge of the side sections of each box-casing 'and in the partition 15, and a bearing-block 17 is held to slide in each box-casing, the bearing-block in the larger casing B being located between its inner side section and the partition 15, as shown in dotted lines in Fig. 1. Each bearing-block is provided with a socket 18 in its upper edge and with a transverse aperture 19, extending through from side to side, and, furthermore, suitable guides 20 are provided for the bearing-blocks, as indicated in Fig. 3. A cross-bar 21 is located within the box-casing B above the bearing-block,- and above the bearing-block in the box-casing B a similar cross-bar 21 is secured, each of the cross-bars 21 .having a downwardly-extending'lug 22. The lugs 22 enter the upper ends of springs 23, the lower ends of the springs being made to enter the sockets 18 of the bearing-blocks, and said springs may be attached at their terminals to the bearing blocks and lugs 22, if found desirable.

A shaft 24 is passed through the slots 16 in the sides of the box-casingsand the partition 15 and likewise through the apertures 19 in the bearing-blocks, and the shaft 24 is provided ,preferably,with a longitudinal slot 25 at one of its ends. Awheel 26 is secured to the shaft 24 or is made integral therewith, as shown in Fig. 4. This wheel is adapted to engage with the floor and is provided with a rim 27, of rubber or a similar material. The wheel 26 occupies such a position on the shaft 24 that said wheel will be centered within the space between the twoboX-casing's, and collars 28 are formed on the shaft 24 at each side of the wheel to prevent the side portions of the wheel engaging with the inner side surfaces of the box-casings.

One end of a spring 29, which may be simi-' lar to the mainsprin g of a clock-movement, is secured to the shaft 24 at its slotted end 25, and said spring, which is coiled upon itself, has its opposite end secured to a cross-bar 30, located in the box-casing B between the partition 15 and outer side section or wall 11.

In operation the door being closed, when the door is opened the wheel 26 will be revolved by contact with the floor, and consequently the shaft 24 will also be revolved, causing a contraction or winding of the spring 29. Therefore when the door is released after having been opened a desired distance the spring 29 will expand and in expanding will cause the door to close, forcing the Wheel 26 to travel in a direction to accomplish this result.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A doorclosing device, comprising a frame provided with independent casings, the side walls and partitions of the casings having vertical slots in their lower ends, springcontrolled bearing-blocks mounted to slide within the casings, a shaft passed through the slots in the casings, through the partitions and through the said bearing-blocks, a mainspring having one end secured to the shaft and the other end to a fixed support, and a wheel secured to the shaft, adapted for engagement with the floor or other surface, said wheel being located between the casings, for the purpose specified.

2. In a door-closer, the combination of a back plate having two casings attached thereto, the casings being separated from each other, the one of the casings having an interior partition forming it into two compartments, bearing-blocks sliding in the second casing and in one compartment of the firstnamed casing, springs pressing the bearingblocks, a shaft mounted to turn in the bearing-blocks, a wheel attached to the shaft and located between the casings, and a helical spring located in the other compartment of the first-named casing and having one end attached to the shaft, the other end of the spring being attached toa part of said casing.

3. In a door-closer, the combination of a back plate having two casings mounted thereon, bearing-blocks mounted to slide in the casings, springs pressing the bearing-blocks, a shaft mounted to turn in the boxes, a wheel attached to the shaft between the casings, and a spring in connection with the shaft, to actuate the same and consequently the wheel.

4:. In a door-closer, the combination of a supporting body portion, bearing blocks mounted to slide therein, means for pressing the bearing-blocks downward, a shaft mounted in the bearing-block, a wheel attached to the shaft, and a spring engaged with the shaft, to actuate the same and consequently the wheel.
